Still, while the Boinc server is capable of finding the best performed application for every particular system, taking into account multiple factors, and after a while it will start sending the right one for every particular system. Which means that even if your CPU is equipped with the FMA engine it still might receive an AVX tasks and there is nothing to be concerned.
